Web Services
Web Service related posts; predominately referential to ASP.Net
It is relatively easy to control access to the various HTTP request types (protocols) for your ASP.Net WebService.
Add something like this to the system.web section of your web.config:
<webServices>
<protocols>
<add name="HttpSoap"/>
<add name="HttpGet"/> <!-- Because this web service is all GET methods -->
<add name="HttpPostLocalhost"/> <!-- So you can test/POST locally -->
<remove name="Documentation"/> <!-- So the outside world can't see your methods documentation -->
<remove name="HttpPost"/> <!-- Remove general POSTs from the outside world -->
</protocols>
</webServices>
Of course you will want to tailor this to the needs of your own web service. :)
